Apples: We have all heard the saying, "An apple a day keeps the doctor away." Does that apply to dogs as well?
Some experts think so. Apples are packed with chemicals that have been shown to kill cancers in animals. Apples also inhibit infectious disease and stabilize blood sugar. A slice or two of fresh apple makes a great treat that many dogs will eagerly devour for the fruit's sweetness.

Barley: A grain that has recently been used more frequently in dog foods. Barley is known to improve bowel function and is thought to possible inhibit cancer.

Broccoli: Known to inhibit cancer and is also a great source of many vitamins, including vitamin A.

Carrots: Are a wonderful source of Beta Carotene, but they contain other vitamins and trace minerals as well.

It then attaches to the valves in the heart causing heart failure.

Cranberry Juice: Known to have beneficial effects on the urinary tract, preventing infections and cystitis. Cranberry juice is also recognized as having strong antiviral properties.

Kelp: It is usually sold dried and ground to a fine powder, often encased in gel capsules. Kelp is an excellent mineral supplement as it is high in iodine, calcium and potassium as well as other trace minerals. Kelp is also known to boost the immune system and kill bacteria. Adds iron to the blood.

Yeast: Is a well-known food supplement; in fact, many dog foods contain yeast as a primary ingredient.
